化学的主要任务之一是发现和制备合成各种有特定性质的新物质来适应时代的发展，结构化学在现代化学发展中扮演重要角色。从高考角度来讲，在全国卷中，《物质结构与性质》作为选考科目之一，近几年福建省内选考物构的人数远大于选考有机的人数。另外由于此模块理论的抽象性和复杂性导致教学困难，因此研究《物质结构与性质》模块意义重大。
本研究结合了《物质结构与性质》模块的知识点内容，结合了高三学生的学习方式和高考中本模块的考试特点，将本模块所需要的化学学习能力分为三个维度：化学记忆能力、化学表达能力、空间想象能力。
通过复习前后两次测试对不同类型的学生的化学学习能力进行横向和纵向的比较研究发现：（1）复习后化学表达能力提高程度最大（2）空间想象能力较低 （3）统招生和择校生存在学习能力差异 （4）学习能力与学生初中毕业的区域无关。
在研究的此基础上，提出针对于《物质结构与性质》的教学建议：（1）在高三复习中，注重记忆能力和表达能力的提高（2）提高高二年学生的空间想象能力（3）因材施教

One of the main tasks of chemistry is to discover and prepare new synthetic materials with specific properties to adapt to the development of the times. Structural chemistry plays an important role in the development of modern chemistry. From the perspective of college entrance examination, in the national volume, "material structure and nature" as one of the selected subjects, in recent years, the number of candidates in Fujian Province, the number of candidates is much larger than the number of selected organic. In addition, due to the abstraction and complexity of this module theory, it is difficult to study the "material structure and nature" module.
This study combines the knowledge structure of the "material structure and nature" module, combines the learning methods of the senior students and the examination characteristics of the module in the college entrance examination, and divides the chemistry learning ability needed by the module into three dimensions: chemical memory ability , Chemical expression, spatial imagination.
(2) the ability to improve the degree of chemical expression (2) the lower the ability of spatial imagination (3) the enrollment and selection of the students (2), and (2) the ability of the students to study the different types of students' (4) The learning ability has nothing to do with the area where students have graduated from junior high school.
On the basis of the study, the paper puts forward the teaching suggestions for "material structure and nature": (1) In the review of high school, pay attention to the improvement of memory ability and expression ability (2) to improve the spatial imagination ability of high school students (3) Teaching in accordance with their aptitude
